Integrated Routing and Switching Technology for LEO Satellites
摘要
Abstract
Low Earth Orbit(LEO)satellites are capable of delivering more precise and efficient multi-source data fusion information services.This paper delves deep into the impact exerted by the on-orbit characteristics of low-orbit satellites on the constellation net-work.Based on this analysis,a payload configuration scheme is devised,which seamlessly integrates multiple service scenarios,includ-ing satellite regenerative processing,transparent forwarding,and sub-band forwarding.In view of the negative effects of constellation network topology changes on service performance and the diverse application mode demands of various user groups,this study con-ducts in-depth research on the design of the low-orbit constellation payload system and satellite-ground integrated routing and switch-ing technology.The research is carried out from four crucial aspects:payload configuration,switching architecture,control mechanism,and inter-satellite high-speed communication.Moreover,the typical performance of routing and switching is validated through rigorous tests.Currently,this technology has been successfully implemented in a specific low-orbit satellite Internet experimental satellite.关键词
